OpenSCENARIO support - PrivateActions

[glopezdiest]

This issue is meant to track the support of PrivateActions within OSC 1.0:

• ActivateControllerAction (Activates CARLA's autopilot)
• ControllerAction
• LaneChangeAction (Some dynamics are still ignored)
• LaneOffsetAction
• LateralDistanceAction
• LongitudinalDistanceAction
• SpeedAction
• SynchronizeAction
• TeleportAction
• VisibilityAction
• AcquirePositionAction
• AssignRouteAction
• FollowTrajectoryAction

Thanks for working on improving support for OSC1.0! 👍
I am especially interested in support for the LaneOffsetAction.
